Chelsea may need to sell forward Eden Hazard “to help fund other transfers”, says ex-assistant boss Steve Clarke.
Hazard, 27, was the match-winner as the Blues beat Manchester United 1-0 in the FA Cup final at Wembley on Saturday.
However, a fifth-placed finish in the Premier League means no Champions League football next season and Clarke told BBC Radio 5 live’s Sportsweek the club must “rebuild” over the summer.
Goalkeeper Thibaut Courtois has also urged the board to invest in the squad.
“We’ll see after the World Cup whether I am a Chelsea player for next year,” said the 26-year-old Belgium international, who is out of contract at Stamford Bridge next summer.
“You see how Manchester City and Manchester United are spending and working.
“If we want to aim for the top, we should do the same – obviously within the limits of what’s possible.
“We’ll see what’s going on and I am sure the board will do what needs to be done.”
